Java uses machines to send keystrokes to humans

I know that robot class can be used to send keystrokes in Java, but is there any way to specify the target process when it has been started?

Solution

The robot sends keystrokes to any application window at the top To send keystrokes to a specific target, you first need to set the target as the foreground window of the platform This may require native code, such as code provided by JNI or (I use) JNA If you want to send keystrokes to the background window, I believe you can't use robot. You must write native code Of course, all native code solutions will depend on the platform

You ask:

For windows, you will work with user32 DLL library Something like this works for me:

User32. java

JnaUtil. java

JnaUtilException. java
